KENT ARTHUR'S

WMmm ror those who like this type of experiment, the test can be a prize example of audience befuddlement. There are performers who will take hold of an experiment of this sort and build it into almost a feature number on their program. Certainly it will not be denied that the method of accomplishing what seems to be quite an impossibility, even for ultra clever mathematically incllnded people, is extremely simple enough to allow of the stunt being practically impromptu.

The performer shows about 20 blank pieces of cardboard.Or he may use his own business cards for the purpose, as they are always left behind with the audience. The people present now call out two figure numbers and these are written upon the cards, a single two figured number to each card, as each card is so inscribed it is dropped Into a bowl or hat and at the conclusion of the procedure any spectator gives the cards a violent mixing.

Now passing to two others of the company, the performer asks each to reach in and draw out a handful of the numbers. Those remaining are kept by the man who mixed the cards and passed the container. During this time the performer has not touched the container or had any part in the procedure after writing the cards when the numbers were oalled.

Standing for a moment before eaoh spectator, the performer gazes Into his eyes and then inscribes something on a small slate he carries. Each of the three spectatorsis now asked to add together all of the numbers he has In his pos-esslon. During this Interval the performer is seen to be adding numbers on his slate. He finally puts down a total and erases the other inconsequential numbers on the slate. The slate is placed writing side down to one side and another picked up.

Each of the three persons now gives his total and these are openly written on the second slate for all to see. A line is drawn tinder them and these, in turn, are added and a total reached. The performer recalls that the numbers used have been selected by the spectatorsat the start and In all selections and adding, the procedures have been entirely under their own control.

Picking up his first slate the performer shows what he wrote at the beginning. IT IS THE SAME TOTAL ARRIVED AT BY THE SPECTATORS!

Little has to be said about the solution for It is awfully simple. The entire swindle, for it Is but little more than that, lies in the cards written upon at the outset. Although the performer asks for two figure numbers called at random from 10 to 99, and then apparently writes each upon a card, he actually writes only HALF as called. For example: The first number called is, say, 28. The performer writes this upon a card and drops it into the hat or bowl. When the second number is oalled HE COMPLETELY

DISREGARDS IT, and really writes that number which, when added to the number called before, will total 100, in this case 72.And so he proceeds thru the cards writing what the audience calls on the odd cards and then what will bring It to 100 on the evens.

NOW IT WILL BE SEEN THAT ALTHO THE CARDS BE MIXED ETERNALLY AND ADDED IK ANY COMBINATION. THE GRAND TOTAL OF 20 CARDS WILL ALWAYS BE 1000. More than 20 or less than 20 cards will give proportionate grand totals, figuring 100 for each pair of two cards.

1000 would be a suspicious total, so to offset this defect the performer on the last card deliberately adds a number which would be more than 100, or less than 100. For instance the number called on the next to the last card might be 73. On the last card, Instead of writing 27 as should be done (to make 100 total for the two cards), the performer could write 51, or 24 more than necessary. Now the grand total will be 1024 Instead of an even 1000. By writing a number less than 27, the grand total would be correspondingly less than 1000.

An alternate and very easy way to accomplish this "different total" at each performance Is to have an extra, or 21st, card. The performer follows the rules through the first 20, each pair totalling 100. On the last card he writes exactly what is called and that number Itself, added to 1000, will be the grand total. This eliminates any figuring upon the performer's part. The audience automatically makes the grand total different each time merely by naming the last, or 21st, number.

Be 3ure to make a great show of mixing and the selection of the numbered cards. Keep away from the operations after the start ao that it all appears more than fair. The audience gets tangled up In the simple solution, always looking for a complicated maze of formulae. For the performer who likes his showmanship and can exult in barefaced deceit (for entertainment purposes only? Ed.) this is a worthwhile secret.
